(l-r) Herbert Lehr, Harry K. Daghlian Jr., Louis Slotin, and unknown. Physicists Slotin and Daghlian would both eventually die from radiation poisoning at different times from the same atomic weapon core.
Louis Slotin, a colleague of Daghlian's, was killed in 1946 while performing criticality tests on the same plutonium core. [6] After these two incidents it became known as the "demon core", [11] and all similar criticality experiments were halted until remote-controlled assembly devices were more fully developed and available. [10]
The demon core (like the core used in the bombing of Nagasaki) was, when assembled, a solid 6.2-kilogram (14 lb) sphere measuring 8.9 centimeters (3.5 in) in diameter.. It consisted of three parts made of plutonium-gallium: two hemispheres and an anti-jet ring, designed to keep neutron flux from "jetting" out of the joined surface between the hemispheres during implosi
When the screwdriver accidentally slipped, the cups closed around the plutonium, sending the assembly supercritical. Slotin quickly disassembled the device, likely sparing others in the room from lethal exposure, but Slotin himself died of radiation poisoning nine days later. The demon core was melted down and the material was reused in other ...

Harry K. Daghlian's hand 9 days after he had manually stopped a prompt critical fission reaction during an accident with what later obtained the nickname the demon core. He received a dose of 5.1 Sv, [18] or 3.1 Gy. [19] He died 16 days after this photo was taken. Cutaneous radiation syndrome (CRS) refers to the skin symptoms of radiation ...
